Importance: Pragmatic clinical trial designs have proposed the use of medical claims data to ascertain clinical events; however, the accuracy of billed diagnoses in identifying potential events is unclear. Objectives: To compare the 1-year cumulative incidences of events when events were identified by medical claims vs by physician adjudication and to assess the accuracy of bill-identified events using physician adjudication as the criterion standard. Design, Setting, and Participants: This post hoc analysis of a clinical trial assessed the medical claims forms and records for all rehospitalizations at 233 US hospitals within 1 year of the index acute myocardial infarction (MI) of 12 365 patients enrolled in the Treatment With Adenosine Diphosphate Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events After Acute Coronary Syndrome (TRANSLATE-ACS) study between April 1, 2010, and October 31, 2012...

REVIEW
Xuezhu Li, George Bayliss, Shougang Zhuang
Renal disease caused by cholesterol crystal embolism (CCE) occurs when cholesterol crystals become lodged in small renal arteries after small pieces of atheromatous plaques break off from the aorta or renal arteries and shower the downstream vascular bed. CCE is a multisystemic disease but kidneys are particularly vulnerable to atheroembolic disease, which can cause an acute, subacute, or chronic decline in renal function. This life-threatening disease may be underdiagnosed and overlooked as a cause of chronic kidney disease (CKD) among patients with advanced atherosclerosis...

RATIONALE: Cervicocephalic artery dissections, once considered a rare disease, have become increasingly recognized as a cause of stroke in young and middle-aged individuals. Early diagnosis is mandatory because anticoagulation or antithrombotic therapy can help prevent primary or secondary ischemic events. However, the diagnosis is still a crucial challenge for radiologists and neurologists. PATIENT CONCERNS: We reported a rare case of 33-year-old patient with progressive ischemic stroke due to dissection from an intimal tear in the right proximal internal carotid artery to distal middle cerebral artery...

BACKGROUND: Serum calcium concentration (Ca) plays an essential role in a vascular muscle tone and myocardial contractility. Previously, we showed that acutely lowering Ca by hemodialysis reduced arterial stiffness. Cinacalcet is a calcimimetic that lowers Ca and parathyroid hormone (PTH). The aim of the present study was to examine whether acute lowering of Ca by cinacalcet improves vascular stiffness and myocardial diastolic dysfunction. METHOD: This is a double-blinded randomized placebo-controlled crossover study that included 21 adult patients with end-stage kidney disease undergoing chronic hemodialysis...

INTRODUCTION: Pulmonary embolism (PE) is a life threatening preventable medical condition involving sudden occlusion of arteries within the lungs. Systemic lupus erythematosus (SLE) is an inflammatory disorder and therefore independently poses a risk of PE. We aimed to determine the association of SLE and PE using National Hospital Discharge Survey data, a national representative sample of hospital discharges throughout the United States. METHODS: Retrospective population-based analysis was done using National Hospital Discharge Survey data for the period 2001 to 2010...

Kawasaki disease (KD) is a form of systemic vasculitis. Regarding its pathogenesis, HAMP gene encoding hepcidin, which is significant for iron metabolism, has a vital function. In this study, we recruited a total of 381 KD patients for genotyping. Data from 997 subjects (500 subjects from cohort 1; 497 subjects from cohort 2) were used for analysis. Using TaqMan allelic discrimination, we determined five tag SNPs (rs916145, rs10421768, rs3817623, rs7251432, and rs2293689). Treatment outcome data related to such clinical phenotypes as coronary artery lesions (CAL), coronary artery aneurysms (CAA), and intravenous immunoglobulin (IVIG) effects were also collected...

The protective potential of ethyl pyruvate (EP) on neuron has been investigated previously. This study was intended to investigate the effects of EP on the severity of oxygen-glucose deprivation (OGD)-induced injury in neural-like PC12 cells. PC12 cells were exposed to OGD condition with or without EP treatment. Then, cell viability, apoptosis, and the expressions of neurotrophic factors were detected. Further, Sprague-Dawley rats were intravenously administered with 5mg/kg EP for 14 days post-middle cerebral artery occlusion (MCAO)...

Background Loss-of-function variants in the angiopoietin-like 3 gene (ANGPTL3) have been associated with decreased plasma levels of triglycerides, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol. It is not known whether such variants or therapeutic antagonism of ANGPTL3 are associated with a reduced risk of atherosclerotic cardiovascular disease. Methods We sequenced the exons of ANGPTL3 in 58,335 participants in the DiscovEHR human genetics study. We performed tests of association for loss-of-function variants in ANGPTL3 with lipid levels and with coronary artery disease in 13,102 case patients and 40,430 controls from the DiscovEHR study, with follow-up studies involving 23,317 case patients and 107,166 controls from four population studies...

Epidemiological studies have identified a robust association between type II diabetes mellitus and Alzheimer disease (AD), and neurobiological studies have suggested the presence of central nervous system insulin resistance in individuals with AD. Given this association, we hypothesized that the central nervous system-penetrant insulin-sensitizing medication metformin would be beneficial as a disease-modifying and/or symptomatic therapy for AD, and conducted a placebo-controlled crossover study of its effects on cerebrospinal fluid (CSF), neuroimaging, and cognitive biomarkers...

Up to 50% of patients presenting with ST elevation myocardial infarction (STEMI) are found to have multivessel coronary artery disease. These patients have a worse prognosis compared with the overall STEMI population. Two revascularization strategies are possible for these patients: treating the infarct-related artery percutaneous coronary intervention (IRA-PCI) only or achieving Complete revascularization (CR), either through an immediate multivessel PCI during the index angiography or during a second-staged procedure...

The present study investigated the feasibility, tolerability, and adherence of daily consumption of whole pulses (dried beans, peas, lentils, chickpeas) by individuals with peripheral artery disease participating in an 8-week study. Study questionnaires and semi-structured interviews for 26 participants were used to determine prestudy pulse consumption and participants' experiences with respect to adherence, positive and negative effects, bowel routine, satiety, and enjoyment of the foods. Although the majority of participants rarely consumed pulses prior to the study, there was a high rate of adherence to daily consumption of the study foods for 8 weeks despite comments regarding study fatigue during the latter part of the study...

Kuller and Reisler's 1971 publication (Am J Epidemiol. 1971;93(1):1-9) was an important contribution to the understanding of the epidemiology of cardiovascular diseases, particularly stroke. The authors synthesized pathological and risk-factor evidence to theorize why rates of various subtypes of arterial disease might vary across populations. Specifically, they suggested that different population levels of blood pressure, lipids, and glucose led to population differences in the location and extent of arterial disease...

We assessed the relationships among adult height, coronary artery calcium (CAC) scores, incident atherosclerotic cardiovascular disease (ASCVD) events, and atrial fibrillation (Afib) in a multi-ethnic cohort. We used race/ethnicity -specific height (dichotomized by median and quartiles) as the predictor variable within the four race/ethnic groups in the Multi-Ethnic Study of Atherosclerosis (N = 6,814). After a mean of 10.2 years of follow-up (2000-2012), 556 ASCVD events (8.2%) and 539 afib events (7.9%) occurred...

Atherosclerosis is a chronic arterial disease and the leading cause of stroke and myocardial infarction. Micro-RNAs (miRNAs or miRs) have been reported to act as essential modulators during the progression of atherosclerosis. Although miR-let-7g has been demonstrated to contribute to maintaining endothelial function and vascular homeostasis, it is not known whether miR-let-7g exerts a therapeutic effect on experimental atherosclerosis. The aim of this study was to investigate the effects of miR-let-7g on atherosclerosis in vivo and in vitro and to explore its underlying mechanisms...

BACKGROUND: Most acute coronary syndromes are caused by the fracture of a vulnerable atherosclerotic plaque. These plaques are thin cap fibroatheromas, which can only be detected with invasive coronary imaging techniques. It is necessary to find a non-invasive biomarker of these vulnerable plaques in order to identify patients at risk without a coronary angiography. Metalloproteinase-1 is an enzyme involved in extracellular matrix metabolism which has been correlated with the rupture of atherosclerotic plaques...
